I've been trying to play music my Pixel 6a (Spotify) in the car, but so far no luck. My car has USB-A ports, and I'm using a A to C cable to connect the phone. It charges fine, but that's all I get.
I've tried all 3 options of USB peripheral access, but it won't play audio through the port.
I've confirmed in developer settings that Disable USB Audio Routing is off as well.
Any tips? Or just not possible?
